Chris Engdahl has graciously offered to post his presentation from last year (2008).
This is a very good powerpoint and might be a starting point to organize your presentation. But remember, I want to encourage originality, so do not feel constrained by this format. You do not need to use powerpoint. You could do a presentation with overheads, or using the board, or using handouts. Remember also, sometimes less is more. I would recommend no more than 14 slides.
